DOTTING ATTACHMENT FOR PENS.

SPECIFICATION forming part of Letters Patent No. 681,574, dated August 27, 1901.

Application led April 5, 1901. Serial No. 54,472. (No model.)

To a/ZZ whom t may concern.:

Be it known that I, HENRY OETTINGER, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of NewYork, have invented a new and Improved Dotting Attachment for Pens, of which the following is a full, clear, and exact description.

This invention relates to improvements in devices designed to be attached to a ruling or other pen when it is desired to make dotted lines; and the object is to provide a simple device for the purpose that may be readily attached to any form of pen.

I will describe a dotting attachment for pens embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the figures.

Figure 1 is a front view of the attachment; and Fig. 2 is a section thereof, showinga pen as secured in place.

The attachment comprises a casingl of any suitable length to form a handle and into which the handle 2 of the ruling-pen or penholder is to be received, as indicated in Fig. 2. This casin g 1 is open at one side, and mounted to slide on its rear wall is a pen-carrying plate 3. This plate 3 has lugs or pins 4L eX- tended through slots in the wall of the casing, and on the inner surface of this plate 3, near its lower end, is a fixed clamping-jaw 5 and a movable screw-pressed jaw 6. These jaws are designed to engage tightly with the penholder or with the shank of a ruling-pen, as indicated in Fig. 2. One side of the casing 1 has its lower end extended downward, as at 7, and pivoted on thel lower portion of this downward extension is a wheel 8, designed to bear upon the paper when using the instrument, and attached to this wheel 8 or to its shaft is a cam-wheel 9, with which the lower end of the plate 3 is designed to engage.

In operation when the pen is secured in the device the device is to be rolled over the paper upon which the dotted line is to be placed, and during this movement the camwheel 9 will cause an upward movement of the plate 3, consequently carrying the pen upward and out of engagement with the paper; but as the recesses 0r depressions of the camwheel getin line with the end of the plate 3 the said plate, with the pen, will fall by gravity, permitting the pen to make adot on the paper.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- I. A dotting attachment for pens, comprising a casing forming a handle and adapted to receive the pen holder or handle, a roller mounted on the lower end of said casing, a cam-wheel mounted to rotate with said roller, a plate mounted to slide in the casing and operated by the cam-wheel, a fixed jaw on said plate, and a movable jaw on said plate, substantially as specified.

2. A dotting attachment for pens, comprising a casing into which the entire length of the pen holder or handle may be received, the said casing being open at one side, a roller mounted on the lower end of said casing, a cam-wheel on the shaft of said roller, a plate mounted to slide in the casing and engaging with said cam-wheel, and clamping devices on said plate, substantially as specified.

In testimony whereof I have signed my name to this specification in thepresencc of two subscribing witnesses.

HENRY OETTINGER.
